Sliver preparation

A method for operating a drafting system having an exit roller pair and at least one additional drafting system roller pair and/or apron roller pair, the method comprising:

• supplying a sliver to a spinning station of an air-jet spinning machine for producing a thread to a vortex chamber of an air-jet spinning device of the spinning station;
• decoupled driving of the exit roller pair from the at least one additional drafting system roller pair and/or the apron roller pair;
• driving the exit roller pair at a predetermined combing-out speed for combing out the sliver after an interruption of spinning;
• wherein the at least one additional drafting system roller pair and/or the apron roller pair located upstream of the exit roller pair in the sliver running direction is stopped or operated at a holding speed which is associated with the combing-out speed and which amounts to a max. 10% of the combing-out speed;
• and
• stopping the drafting system combing and then powering up the drafting system for piecing.
